Good idea, Almerin!
If I remember correctly (and i may not, since I haven't actually read the Hobbit in
years ) the fellows name was Beorn (sp?).
Assuming that's the correct answer, of course, the next question is this (continuing with a theme):
Gimli from the LotR Trilogy is the son of one of the dwarves that accompanies Bilbo in The Hobbit... Which dwarf was Gimli's father?
